Specification of Letters Patent.`

rateatea ,any s, 191e.

To all 'whom t may concern Be it known that i, GEORGE W. FOSTER, a citizen of the United States, residing at Providence, in the county of Providence, State of Rhode island, have invented eertain new and useful improvements in Winding-Machines, of which the followingiis a specification. My invention relates to winding machines and particularly to cone-winders of the drumor friction-driven type. it has for its object toprovide an improved mechanism for winding yarn or other textile materials into conical packages 'while building the cones with a gradually increasing taper from their i/nner to their outer layers, whereby to insure a free and unrestricted delivery of the yarn in unwinding it therefrom. vrThe peculiar method of building the eone'to secure this increasing` taper on its surface from its interior to its exterior consists essentially in periodically stepping back the courses of the yarn-coils at. intervals of the winding to dispose a thicker mass of material at the base of the cone than at the apex end. rThis method is disclosed in my U. S. Let-ters Patent No. 1,233,041,

dated July 10, 1917, and oneorm of traverse-mechanism 'for effecting the shortening and lengthening of the throw of thethreadguide., which deposits the yarn-coils in placeon the cone, is described and illustrated 'in my U. S. Letters Patent ilo. 1,233,042, dated July l0, 1917.

' .lvfiy present invention is directed to the winding-mechanism in general and consists of improvements in the structure and method of operation ot the compiete machine as fully described in the following specifica-tion, illustrated by the accompany ing drawings, in which like reference char acters designate like parts. Tn the draw ings Figure 1 is 'a front elevation of a portion of the machine frame or stand, showing the arrangement oit' the several winding-units mounted thereon; A

Referring first to Figs. lf and 2, my improved machine is preferablyconstructet in gang t'orm with a. pll'lrality of windinIg-units mounted on a stand or frame F. Tie trame F may be of any suitable construction and as here illustrated comprises the longitudinal rails or side-members 2, 2 supported at their endsby standards 3 provided with feet, not here shown, which may be bolted to the Hoor on which they stanch Journaled-'in bearings i bolted to the end- 'rames 3 is the main drive-shaft S which .On the outer end ot the drive-shaft S are tight and loose pulleys P, P which may be connected by a belt, not here shown, te the motor or other prime-mover from which the machine is driven. shipper-fork U, see 2, is slidable on a rod 5 and mayY be operated by the handle U to sh-itt the belt from the loose pulley i3 to the tight' pulley P. and vice versa, to start or stop the machine. Fast on the shaft- S at the opposite side o the endrame F is a gear meshing with a larger gear which is keyed or otherwise secured on an upper shaft S". rihe shaft S is journaled at its outer end in :t bearing 8 bolted to the standard 3, and'extends through bearings 9, 9 in two brackets E, H which depend-'from the side-rails 2, 2. As shown in Figs. 3 and si the brackets H, H are termed with arms 10, 10 which overlap the top' of the side1ails 2 and are bolted thereto. it their lower ends the brackets H, H are connected by a drip-pan H so that the whole structure forms a sort or" casing or housing for the traverse-cam TC l *which is mounted ixedly on the upper shaft S. Preferably the housing H, H is mounted on the side-rails 2, 2 midway between the end-frames 3 and the single cam K serves as the main driving element for the whole series of threador yarn-guides G which are reciprocated on opposite sides of the machine in juxtaposition to the cone-holders C spaced therealong. a

Referring again to Figs. 1 and 2, the endframes 3 are provided with bearings for two horizontal shafts R, R which carry the friction-drums .or drive-rolls D, D, etc.-

The shafts R, B are arranged in parallel relation on opposite sides of the machine\ Through this arrangement the shafts R,

B are driven in opposite directions as required to rotate the drive-rolls. D in the manner and for the purpose ashere/inafter more fully explained. An idler-sprocket 20 is journaled on a shatJ 21 at the end of an arm 22 and the driving chain passes over it, as shown in Fig. 2, to take up the slack. The arm 22 is pivoted on a stud 23, screwed into the side of the end-frame 3,( to adapt it tobe swung about the axis thereof to adjust the position of the idler 20. A bolt 24 reaches through an arcuate slc-t 25 in the arm 22 and extends through a hole in the frame 3 with a nut-26 at its end. The nut 26 may be loosened to adapt the arm 22 to be adjusted on its pivot 23 and by tightenlng it again the bolt 24. will act tov clamp the arm in position against' unwarranted movement. f

Extending horizontally the length of the machine is a tie-rod T secured at its ends in bearings at the top of the frames 3, 3, see Figs. 1 and 2. Spaced at intervals along the rod lT are, a plurality of depending brackets 28, 28, which support a lower, parallel rod "l", see also Figs. 4, 5 and 6. The brackets 28, 28 are extended below the rod T, and vsecured therein are pins or [studs 29 on which are pivotally mounted the swinging arms A 'for supporting the sm/all ends of the cone-tubes or mandrels C on which the packages are wound,.se Figs. 4 to 6.4 The opposite or base end of each cone-tube C is supported by an arm B which is pivoted on the rod T. Through this .arrangement the larger'or base end of the cone 'is caused to swingabout an axis elevated above the axis of the pivot about which the small or apex end .swings in the in Figs. 5 and 6 the arms B, B are arranged in pairs disposed in opposite relation between each pair of brackets 28, 28. The arm B of each pair supports the base end of the cone-tube C at one side of the machine while the other arm B extends in the opposite direction to support the cone-,holder on the other side of the machine. vThe arms B and B are located in position longitudinally of the rod T by means of collars 32, 32 secured to' the rod T by set-screws 33. Each. collar 32 is.formed on its side with an inclined cam-face 34 against which a lug 35 on the hub 30 of the arm B rides, see detail v-iew, Fig'. 8. The lug 35 is form/ed on the side of a ange 36 at the end of the hub 30, and bearing against the opposite side ofthe ange is a plate or washer 37 which takesthe thrust of the spring 31. The washer 37 is formed with spaced arms 38, 38, see Fig. 7,

which straddle the sides of the upper rod T to hold the washer from turning. As shown in Fig. 6 the spring 31 acts against the hubs .30 of both arms B and B to maintain their lugs 35 bearing against the cam'- faces 34, and the purpose of theJ -washers 37 `is to prevent the swinging movement of the 32 to slide the arm bodily to-Athe right against the action of the spring 31. Likewise, the upward movement of the arm B",

will cause its lug 35 riding on the incline 34 of the collar 32 to slide Athe arm'to the left onthe rod T. Through this arrangement the cone-holders C are causedto be displaced longitudinally of their respectivedrive-rolls in -a substantially axial direction. This axial displacement of the cone ioo is'in theV direction of its apex endvand is relatively sli ht,v being designed to overcome the tend with an excessive concavity atf its nose. Tl'ns tendency 'arises from the inclined relation of ency' ,of the cone to build up the axis of 4theJ conel to' the surface of the drive-roll and in the present type of machine this inclinationbecomes greater as the cone buildsup with van increasing taper ofv its surface. The purpose of the above described 'arrangement 'for shifting the cone along its drive-'roll is more fully explained in myvpending U. S. application for patent, Serial No. 124,373, tiled Oct. 7, 1916, the

present mechanism Aembodying certain improvements in the structure and method of operation of the device.

assegna Rei'errin still to Figs. 5 and 6, the apex or nose en of each cone-holder C is supported at the end of the before-mentioned arm A, which carries a bearing .arranged as follows: Pivoted on the Stud 29 which projects from the side of the bracket 28 is a hub 40 held between the side of'the bracket and the cap-like bearing 41. The cap 41 is formed with a nut 42 screwedonto the reduced end 43 of the stud 29 and locked in place by a check-nut 44. The inner tace of the cap 41 is concaved to receive a relatively thin, dished spring-washer 45 which bears Yagainst the side or the huh 40, thereby tending to regulate the swinging movement of the arm A about its axis. rihat is to say,

`the spring 45 acts to rictionize the turning of the hub 40 on thes stud 29 and thereby serves to resist the movement of the arm A as theenose of the cone recedes from the drive-roll. rlhe purposeI of this arrangement is to insure a firm contact of the nose end of the cone against the drive-roll D which imparts rotation thereto. .as shown more particularly in Fig/5, the hub 40 is formed with a short arm .46 to the side (if which is hinged the main arm The arm A is connected to the arm 46 by a pivot-pin 47 and is formed with a pocket 48y for receivin the; end of a helical spring- 49.I The opposite end of the spring 49 bears' against the sideo the arm 46 to 'maintain the end of the larim A in position to recei-ve the apex( or tip of the cone-holder C, while also providing for the axial displacement of the cone when the arm B is slid along the rod T', as previously explained. As shown in Figs. 5 and 6 each stud 29 supports a pair of hubs 40 for two oppositely extending arms A, A',

the latter supporting the cone-holders of.

two winding-units on opposite sides of the machine.

Referring now particularly to Fig. 9, the cone-holder C is preferably of conventional orm consisting of a conical tube havin-g relatively thin walls, usually or' paper or fiber, converging at one end in the rounded nose c. The nose@ is adaptedto be fitted into a cup-like member 50 mounted in a ball-bearing at the end oi the arm fa. any suitable 'forni of bearing maybe employed for this y j( purpose and as here shown the cup 50 carries a ball-race 51 on its periphery adapted vto engage a series of balls 52 rolling in a corresponding race 53 held in an opening 54 in the end of the arm rEhe opposite, base end of the cone-tube C tits over the tapered periphery of a ring or bearing 55 which is formed with a hub 56 carrying a ball-race 57. Projecting from the side of the arm B is a stud 58 formed with a head 59 having its inner side concaved. The stud 58 is inserted through the bore 60 of a sleeve 61, the outer end oi-x which is of convex formation to adapt it to it the concavity oi'i the head 59. rihe inner end of the sleeve 61 is slightly enlarged in a flange 62 having its side formed convexly to adapt it to fit into a corresponding concavity 63 in the arm B. @n the periphery of the sleeve 61 is a ballring or race 64 arranged opposite the race 57 with theballs 66 revolving therebetween. A cap 67 is screwed onto the sleeve 61 to hold the race 64 in place against a shoulder 68, said cap being formed with a fiange 69 :tor retaining the Lbearing-ring 55 in position with the balls 66 in proper relation to the races 57 and 64. it will be noted that the bore oi the sleeve 61 is of greater diameter than that of the stud 58 to provide sufcient play for the sleeve to rock slightly on its bearing. r@hat is to say, the sleeve 6l which carries the bearing-ring 55 is free to move in the manner of a` ball-and-socket joint,. the purpose 0f the arrangement being to allow the cone C 'to change its angle of inclination to the driving-drum D as it recedes therefrom with the growth inthe winding.

Referrin now to Figs. 1 and 4, the arm B is slottec along its top at 7 0 and pivoted in the slot on a. cross-pin 71 is a lever 72. rlhe outer end of the lever 72- is provided with a finger-piece 7 3, while its inner en'd is formed with a hook 74, the extremity lof which normally rests on the top of the tierod T. As the arm B swings upwardly' during the building of the cone the end of the hook 74 rides around the periphery of the rod T without interferingwith the movement of the arm. .hen, however, it is vrequired to raise the cone away from Contact with the drive-roll D in piecing up the yarn or in applying the cone-tube C to itsholder and in doiiing thecompleted package, the arm B is lifted Jfar enough to allow the end oi" the lever 7 2 to hook around the'rod T. rihrough this means the arm B may be suspended in raised position to facilitate the application of the cone-tube C to the supporting arms A. and B and the removal of the completed package; and by pressing down on'the outer end of the lever 72 its hook 74 can be released to allow the arm to be lowered into operative position as shown in Fig. 4. weight lV, shown in Fig. 4, is usually attached to the side of the arm B to maintain the cone or package rmly against the surface of the drive-roll D during the winding, this element being omitted from the other views so as not to confuse the showing 0i the other parts.

The thread-guides G which operate to traverse the yarn or thread back and forth along the eolie-tubes C duringotheir rotation from the drive-rolls D fare carried by two longitudinally reciprocable traverse-bars E mounted on opposite sides'of the machine. rThe bars E are preferably or rectangular shape in cross-section and are mounted to slide in slotted bearings 7 5 which are formed The guides Gr are constructed of sheet-metal formed to fit around the sides of the bars E j and secured in place by screws 76. Each guide G has an arm 77 reaching in toward the drive-rollvD with its end bent upwardly at a point adjacent the line of contact of the cone-tube C on the surface of the `roll. Formed'inthe top of the guide G is a slot g, see Fig. 3,-for receiving the yarn or other strand to be wound onto the tube C. Each traverse-bar E carries a plurality of thread guides G equa-l in number to the whole number of winding-units on its respective side of the frame F. As before stated a single cam K serves to traverse all of the thread-guides on both sides of the machine, and this is. connected to reciprocate the two traverse-bars E as next described.

As both traverse-bars E have the same arrangement of vconnection with the cam K it will suffice 'to explain the mechanism for one only, reference being had particularly to Figs. 1, 3 and 4. The camK is mounted fast on the upper shaft S between the brackets H, H, and is of usual construction havinga hub 80 with spokes 81 radiating therefrom to support the circular rim 82. In the rim 82 isla helical groove 83 adapted to receive a roll 84 which is rotatable on a stud 85 projecting from the side of a slide or crosshead 86, see'Fig. 4. The crosshead 86 slides on two rods or tracks 87, 88 extending between the sides of the brackets H, H. For the lower track 87 a round rod is em I ployed, adapted to tit the circular bores 89 .of two bearings 90,- 90 at the ends of the ope positely extending arms 91, 91 of the cross- .head 86. At the top ofthe crosshead 86 is a central bearing 92 formed withSu a rectangular s'lot 93 fitted to the sides of the upper, square rod or track 88. The stud85 .which carries the camp-roll 84 is bored axially to receive a smaller stud or pivot-pin 94 which rojects from theJ side of a bell-cranklever to'connect the latter pivotally with the crosshead 86. The bell-crank L has two arms 96 and 97 disposed at an angle of substantially ninety degrees and connected by a diagonal brace 98. At the end of its vertical arm 96 is a stud 99 on which is journaled a roll 100. The roll 100 is adaptedto play up ,and down in a slot 101 formed in a member 102 secured to the traverse-bar E. Prefer-v ably the member 102 is constructed-of sheetmetal with ears 103 bent around the sides of the traverse-bar E and 'welded or riveted thereto. The main portion ofthe member 102 extends below the bar E and is .cut away at its'center to provide two ears 105', 105 bent out to form the opposite, parallel sides of the slot 101 for the roll 100. On its outer sides the member 102 has its edges bent over to provide two flanges or abutments 106, 106

At the outer end of the horizontal arm 97 A of the bell-crank L is a block 1 10 pivoted on a pin 111 projecting from the sidel of the arm. The block 110 is fitted to slide .in a

rectangular slot or guiding-track 112 in a builder-arm O which is of channel like form in cross-section as shown more particularly in Fig. 4. Projecting from the side of the trackor builder-'arm O is a stud or pin- 114 pivotally mounted in a bearing 1,15, which depends from a bracket 116, and held in place by a Cotter-pin 117, see Figs. 1 and 4. The bracket 116 is bolted to the sideflange 118 of the longitudinal frame-member or rail 2 which is of inverted troughshape in cross-section as shown in Fig. 4. At the outer end of the builder-arm O is an extension 119 formed with a reve-rsely curved cam 120 on its under side. Adapted to wipe across .the cam 120 is a .roll 121 journaledon a pin 122 carried at the end of a meshes with another gear 132 which is fast 100 on the upper drive-shaft S. Through this/ train of gearing the shaft S rotates the shaft 124 at a relatively slow rate of speed to .turn the crank-arm 123 in the direction indicated by the arrow Fig. 3, whereby to cause the roll 121 to wipe' `across -the cam 120. By means of this action the builderarm O is caused to rock up and down on its pivot 114, thereby altering its angle of inlate the angular position ofthe bell-crank L as its block travels in @the track 11,2. The arm O is controlled by a spring 1 33 anchored at )one end to a lug 134von-the left' site end to 'an arm 135 reaching down from the under side of the arm. It will be noted from reference to Fig. 3 that the roll 121 on the crank-arm 123 enga-ges first with the relatively`short, convex portion 140 ofthe 1'20 cam to lift the track or builder-arm O against the action of its spring 133; but asthe roll passes Jover the point 141 of the cam and travels around its concaved portion 142 the arm Q vwill be allowed to rock downwardly under vthe influence of the spring 133. 'As the roll rides 0El from vthe end ofV the portion 142 of the cam 1 20 the ldownward movement of the arm O is arrested by a stop-screw '143 which strikes against the 130 clina'tion to the horizontal, whereby to regu 11d hand bracket H and connected at its oppo- '115 Lacasseatted side 144 of the bearing 126 on the. bracket H. The screw 143V is screwed into a lug 145 on the side of the cam 120 and is adjustable to regulate the extent of th'row of the arm as required, a check-nut 146 being employed to lock it against unwarranted turning.

Projecting upwardly from the top of the builder-arm O is a relatively thin, fiat spring 147 secured to an extension 148 of the cam 120 by means of a screw 149. 'jlhe upper end of the spring 147 is bent into a curved abutment 150 which is adapted to engage the side ofthe flange 106 on the traverse-bar member 102 when the latter reaches the righthand end of its throw, as viewed in Fig. 3. A. corresponding spring. 151 is fastened to the top of the rail 2 at 152 and formed with an abutment 153 at its upper end for engaging the opposite flange 106 on the member 102 when the traverse-bar E moves in the reverse direction. rjlhe two springs 147 and 151 are thus caused to act as buers to take the shock of the reciprocating motion of the traverse-bar E to assist the reversal of throw of the latter at the ends of its traverse. rEhe spring 151 is stationarily supported, since the left-hand extreme of traverse of the bar E is ixedly determined; while, on the other hand, the positionof the spring 147 varies with the displacement of the track or builder-arm Q whereby to insure the proper coaction between the end of the spring and the member 102 when the extent of traverse of the bar E is altered at its right-hand end. This shortening and lengthening of `traverse of the bar E and its thread-guides G is effected through the periodical displacement of the track or builder-arm t) which rocks the bell-crank-lever L on the crosshead 816 during the continuous operation of the machine as more fully explained hereinafter. T he coaction of these elements of the builderor variable-traverse-motion is substantially the same as that explained in my U. S. Patent No. 1,233,042, July 10, 1017, before referred to, although the construction and arrangement of the elements is somewhat different as will be seen.

The tension-devices, which apply tension to the yarns as they draw from their supply bobbins to the package being wound, may be 0f any Suitable construction and as shown in Fig. 4 are arranged as follows: Secured to the flanges 118 of the horizontal side-rails 2 of the machine-frame F are a plurality of brackets or arms 155 which support two Iongitudinal bars 156n arranged on opposite sides of the machine. Only one of. these bars is shown in Fig. 4, as both are arranged in `the same manner on opposite sides of the fra-me F as shown in Fig. 2. Space/rl at intervals along each bar 156 in appropriate relation to the several windingunits are the tension-devices `\l. A s shown in Fig. 4 each tension-device N comprises two opposed disks or washers 157 rotatably mounted on a pin 158 with one or more weights 159 acting to press them together. Projecting from either side of the bar 156 are wire arms 160-160a which are bent into loops at their ends to adapt them to guide the yarn or thread y as it leads between the tension-disks 157, 157. From the tensiondevices N the yarns y lead to the threadguides G across a sheet-metal apron or guard-plate J which extends the whole length of the machine, being fastened at the ends of arms 161 projecting from the front of the bearing-brackets 12.

A horizontal rock-shaft 162 is journaled in bear-ings 163 in the arms 161 and pivoted thereon is a plurality of arms 164 extending outwardly beneath the tension-devices N and rearwardly toward the drive-rolls D, see Fig. 10. Pivotally mounted at the outer end of each .arm 164 is a drop-wire 165 formed with a loop 166 at its upper `end adapted to hook over the yarn v/ as it draws between the two guides 16C- 160% At the side of each arm 164 isa stop-.lever 167 formed at its end with a shoulder 168 adapted to be engaged by the lower end of the drop-wire 165. The hub 169 of the stop'- lever I167 is split and secured fast on the rock-shaft 162 by means of a binding screw 170. On the hub of the arm 167 is an ear 171 having a hole 172,4 into which is hooked the end of a rod or bar 173, see Fig. 4. The rod 178 extends laterally across the frame F and at its opposite end is connected to a lever corresponding with the stop-lever 167 to adapt it to serve as a means for oscillating the rock-shafts 162 on both sides of the machine. Biety its center is a pin 174 engaging the upper, slotted end of a lever 175 which is pivoted :1t 176 to the side of the bracket H. The, lower arm of the lever 175 is of bifurcated form arranged with its legs 177, 177

vstraddling the periphery of an eccentric 178 which is fast on the drive-shaft S. As the eccentric 178 rotates with the shaft Sthe lever 175 will be oseillated on its pivot 176 to reciprocate the rod or bar 17 3. This ac` tion rocks the stop-levers 167 to oscillate the shafts 162 on the opposite sides of the frame F. Meanwhile the arms 164 are normally withheld from motion with the shaft 162 and levers 167 by means of their inner extensions 179 which serve as detent arms as next explained.

Referring particularly to Figs. 10 andl 11. each drive-roll D is provided with a cone-lifter Q adapted to be inserted between the surface ofthe cone and the periphery of 4the roll to lift the package from driving contact therewith, whereby to arrest its rotation. rllbe cone-lifter Q is formed with two arms 180-180 straddling the ends of the drive-roll D and pivotcd on bushings g projecting from the ends of the bearings 12,

see Fig. 3, and surrounding the roll-shaft R. Connecting the arms 180-180 is an 't end to a lug 187 on the arm 164 and nor-f mally tends to maintain the shouldered lug 183 on the lifter Q locked with the end of the detent-arm 179 as shown in Fig. 10., When, however, the end of the detent-armV 179 is rocked downwardly it will release the shoulder 184, whereby the spring 186 will turn the lifter Q on its axis to carry its portion 181 in yunder the package or cone being wound. This action raises the cone off from its drive-roll D to arrest its rotation in the manner and for the purpose as later explained. The operation of the cone-lifter Q is automatic and takes place upon the breakage or exhaustion of the yarn being wound. Referring' to Fig. 4, when the yarn y/ fails or breaks, it will allow the drop-wire 165 to tilt, through the action of gravity, to engage its lower end with the shoulder 168 on the stop-lever 167. As before explained the lever 167 which is fast on the rockshaft 162 is constantly oscillated from the eccentric 178 on the shaft-.SQ and -hence when the drop-wire 165 engages its end it Will cause the arm 164 to be moved therefrom to depress its extension 179. The downward movement of theVdetent-arm 179 releases the lug 184 on the lifter Q which is then actuated from its spring 186 as previously explained. For resetting the lifter Q to release the cone while again engaging the detents 184 and 185 a bail-like handle 190 isA provided on one of the arms 180. The

bail 199 is preferably formed of wire with its inner end bent at right-angles and hooked into a hole 191 in the `arm 180 of the lifter Q. The outer end of the bail 190 reaches through an opening 192 in the apron J and is bent into a loop 193 to provide a handle for pulling it outwardly to rock the lifter to remove it from under the cone.

The method of operation ofthe complete machine is as follows: The paper cone-tubes C are first applied/ to their supporting arms A Vand B by inserting their rounded noses c' into the bearing-cups 50 and fitting their base endsover the conical bearingrings 55, see Fig. 9. The hinged arrangement of the arms A adapts them tc yield to provide for slipping the cone-tulbes onto their supporting-'rings 55,-and when released their springs 49 cause them to press against the nose ends of the tubes to hold their base ends snugly in place on the rings. During the operation of applyingV the cones-to their supports the arms B may be suspended in raised position, if desired, by hooking the ends of the levers 72, shown in Fig. 4, around the tie-rod T. After the cone-tubes are in place the levers 72 are released to allow the arms B to drop and each tube will then come down against the bridge-piece 181 of the cone-lifter Q as shown in Fig. 11.

The yarns 3/ to Ybe wound into the cones draw off from supply-bobbins Y arranged below as shown in Fig. 2, and lead up across the guide-wires 1603, between the tensiondisks 157 and'under the drop-wires 166 and guides 160, see Fig. 4. Thence the yarns y lead across the guard or apron J to the thread-guides Gr, being inserted through the slots r/ and secured to their respective conetubes C by winding their ends therearound. The threading up of the yarns may be done while the arms B are held suspended by their hook-levers 72 if desired, this being the preferred practice as more convenient for attaching the ends of the yarns to the cone-tubes. The machine is now ready for winding, each unit being started separately, and as all of the winding-mechanisms are the same, it will suffice to explain the method of operation of only one After the cone-tube C has been lowered into position above the drive-roll D the bail 190 is pulled forward. and this action rocks the lifter Q on its axis to withdraw its bridgepiece 181 from under the tube, as shown in Fig. 10, whereby its surface will be engaged by the periphery of the roll D to be rotated therefrom. As the lifter Q is rocked around the shaft R against the tension of its spring 186 lthe end of its lug 183 rides over the curved end ofthe arm 179 until the detentreciprocate the cross-head or slide 86 back and forth on its tracks 87488. The slide 86 carries the bell-crank-lever L which is connected by its arm 96 to the traverse-bar E, and therefore a rectilinear," reciprocating motion will be imparted to the thread-guides G on the bar to traverse the yarn on the cone-tube C. in spiral coils or helices inthe manner wellknown to those versed in the art. As the bell-crankAL moves back and nasca-.ice

-turns in the direction indicated by the arrow Fig. 3, as rotated by ,its shaft 124.- through thetrain of gearing 127, 128, 130, 132 driven from the cam-shaft S. rlhroughout the greater portion of the building of the cone von its tube C the arm 123 is inoperative,

its roll 121 revolving through that part o f its orbit which is removed from the path of the cam 120 on the builder-arm O. During this'period the track 0 will be inclined downwardly to the right with its stop-screw 143 resting against the flatted side 1411 of the bearing 126. With the arm 0 remaining at rest in this position the. block 110 on the arm 97 of thel bell-crank L slides down the incline as the crosshead 86 moves to the right and hence 4the lever L will be rocked on its pivot 94 to give an added incrementof movement to the traverse-bar E connected to its vertical arm 96. rlhe full throw of the cam f K is somewhat less than that required t0 traverse'the thread-guide G from the base to the tip of the cone-tube C, that is 'to say,

as herein shown the throw of the cam is three-quarters the full length of the cone wound on the machine. The additional onequarter length of traverse of the threadguide-over and above the initial throw of the cam is therefore provided bydisplacing the bell-crank L angularly about its pivot 94 on the slide 86. 1n other words, the rocking of the lever L to the right augments the length of its normal stroke with the slide 86 and in this way an increment ofimovement is given to:y the traverse-bar E to provide the full length of traverse for the guides G. While the traverse-motion operates in this manner to wind the yarn the full length of the pack-- age the crank-arm 123 rotates about its axis at a relatively slow rate of speed until eventually the roll 121 atits end comes into engagement with the convex. face 140 on the tion ot' the roll 121` wiping alongthe camface 140 the bell-crank L will undergo a As the arm O gradually diminishing displacement from the action of its block 110 in the guidinggroove 112. That is to say, the bell-crank L will be rocked to the right to a less extent during each traverse of the crosshead 86 to the right so that the length of traverse of the rod E will be correspondingly shortened at the small end of the cone. ln this way the courses of the yarn coils laid onto the cone are progressively shortened or stepped back from its apex end whereby a thicker mass of yarn is built up at its base to eiect the increase in taper on its surface. When the builder-arm 0 reaches the horizontal the angular displacement of the bell-crank will cease and the traverse of the bar E will be equal in extent to the full throw of the cam K. rlhe tiltin of the arm O does not stop at this point, iowever, but on the contrary continues until the right-hand end of the track is inclined upwardly above the horizontal. As the arm 0 rises above the horizontal its effect on the bell-crank L will be the opposite from that which it has when it is inclined downwardly. That is to say, the block 110 on the arm 97 will now travel up' the incline of the track O to rock the bellcrank L to the left as the crosshead 8G slides to the right, and in this way the traverse of the bar E is still further shortened with respect to the throw of the cam K. As the roll 121 on the arm 123 reaches the high point 141 on the cam 120 the arm O will be raised to its maximum extent and the traverse of the guide G will have been shortened to substantially one-half the, full length of the cone. From this point the traverse of the guide G starts to lengthen again as the builderarm 0 is allowed to swing downwardly under the action of its spring 133. The downward movement of the arm O is controlled by the action or" the roll 121 riding along the concave face 142 of the cam 120 and continues until the roll rides 0H' the end of the cam and its stop-screw 143 once more comes into Contact with the bearing 126. TheV traverse of the thread-guide G is thus gradually lengthened again until the maximum is reached which is equal to the full length of the package being wound. The guide G will then continue to be reciprocated with the full length of traverse until the crankarm 123 has again moved around to bring its roll 121 once more into engagement with the outer end of the cani 120. In this manner the depositing of the coils oit' winding onto the cone takes place in cycles, the greater portion of the package being built up with layers of full length, interrupted at intervals by gradually shortened and lengthened courses of the coils. rllhrough this method of laying the coils in place the body of the cone is built up with substantially wedgeshaped sections of shortened and lengthened courses intervening between the full length the package to gradually assume an 1ncreased conicity or steeper pitch.

As the winding builds up in this manner the increase in diameter of the mass causes the axis of the cone torecede from the driveroll D while its surface remains constantly in contact therewith. As the cone rises its supporting arms A and B swing upwardly `on their pivots 29 and T and meanwhile the aXis of the cone becomes more and more inclined to thev face of the drive-roll D, due to the increase in taper on the surface of the cone. During this change in the inclination of the aXis of theJ cone the ring 55 which supports the base end of the tube C will rock slightly on its bearings as provided for by the ball-and-socket jhints ofthe bearing-hub 62, and the clearanceof the stud 58 in its bore 60, see Fig. 9.

As before stated the increase in inclination of the cone with respect to its drive-roll tends to cause its base to be' formed conveXly and its opposite end concaved. To

prevent this tendency from causing an abnormal concavity at the nose of the cone whereby its structure would be weakened the f. whole package is shifted bodily to the right by means of the cam 34 on the collar 32, see Figs.- 5 and 8, which acts against the lug 35 on the flange 36 of the arm B, as previously explained. Through this arrangement the shaping of the cone is determined and controlled within the prescribed limits to provide the preferred formation of its ends.

The winding of the individual cones is arlthe shaft S, through the lever 175 'and rod 17 3. The engagementof the lever 167 with the drop-wire 166 raises the arm 164 to depress its rearward extension 179. This action releases its end 185 from the detentshoulder 184 on the lug 188, see Fig. 10, and allows the cone-lifter Q to rock under the action of its spring 18'6. The bridge-member 181 of the lifter Q is thereby carried in under the cone orpackage to raise it away from the drive-roll D as shown in Fig. 11. this manner the cone is free from driving contact with its drive-roll so that its rotation will cease, and for convenience in repairing or piecin up the broken end it may be raised still furt 1er by hooking the lever 72 around the tie-rod .T as previously explained. The rotation of the package may be arrested manually in the same way Vby simplylifting up the end of the arm 164 te release the detentsg and to start the Winding again it is only necessary to pull out the bail 190 to withdraw the cone-lifter Q, and rengage its detent- I' shoulder 184 with the end 185 of the arm V179. It will be understood of course that the lthread-guides G reciprocate constantly during the continued operation of the machine, it being unnecessary to arrest their motion to thread them since if the yarn` is drawn taut between the cone and the tenmy improved machine without departing from the spirit or scope of the invention; therefore, without limiting myself to the eX- act embodiment shown and described, what T claim is 1.
